SOAP.

N0 Drawing.

To all whom it may concern:

Be it known that 1, PAUL LEON EUGENE PECH, citizen of the French Republic, residing at Narbonne, Aude, in the Republic of France, have invented new and useful Improvements in Soaps, of which the following is a specification.

This invention relates to an improved soap soluble in salt water and capable of washing and foaming in sea water even after a few years manufacture.

An important feature of the improved soap resides in that it contains a determined proportion of chlorate of potash, added to the soap during its manufacture, under the form of a saturated solution.

My invention also comprises an improved soap of this kind, the composition of which will be fully disclosed in the following specification.

I have discovered that if a a976 solution of chlorate of potash i. e. a saturated solution of said salt is added to ordinary Marseilles soap (soap embodying vegetable oil) which is entirely insoluble in sea water. for instance if 66 grammes of said solution are added to 100 grammes of soap, a soap is obtained which is soluble in sea water even after a period of a few years. A solution of chlorate of potash is added to the soap paste by small amounts during the manufacture of the soap and as far as possible without stopping the boiling operation.

An improved soap may be obtained by using the following materials:

Cocoa nut oil about 100 kilograms.

Anhydrous caustic soda. about 2,750 kilograms.

Silicate of soda about 5 kilograms.

Anhydrous caustic potash about 6 kilograms.

4% solution of chlorate of potash about 100 kilograms.

The proportions of basis and silicate above set forth may obviously vary to a certain extent, for instance according to the season and atmospheric temperature in order to always Application filed January 4, 1921. Serial No. 435,014.

give the soap the necessary hardness without exaggeration.

The oil used is preferably cocoa nut oil. The soda is preferably used under the form of a solution at 12 B. and a solution at 19 B.

The soap is preferably prepared as fol lows: The oil is emulsified with a soda lye at 12 B. and the 19 B. soda lye and the silicate are then added. The mixture is heated for a certain time, the potash is then added and heating is resumed until the soap forms a paste. The chlorate of potash is then poured by small amounts as far as possible without stopping the boilin, operation which should continue until all of the water thus added to the soap in the operation has been evaporated, i. e. until the soap thickens again in the kettle in the form of a paste. The latter is then poured rapidly into moulds. 'When the cooking operation is ended the soap should contain about 70% of pure oil.

Having now described my invention what I claim as new and desire to secure by Letters Patent is:

1. A method of fabrication of a soap washing and foaming in sea water which consists in saponifying pure cocoa nut oil by a mixture of anhydrous caustic potash and anhydrous caustic soda, and adding to the paste during the manufacture, a saturated solution of chlorate of potash, the proportion of chlorate of potash being 4% of the weight of the cocoa nut oil.

2. A soap prepared by means of the following materials in the following approximate proportions:

Cocoa nut oil 100 kilograms.

Anhydrous caustic soda 4,750 kilograms.

Silicate of soda 5 kilograms.

Anhydrous caustic potash 6 kilograms.

4% solution of chlorate of potash lOO kilo grams.

In testimony whereof I have signed my name to this specification.
